Mt. St. Helens is an interesting geology field trip in the summer, but winter changes the landscape from dust-grey to blinding white. When snow closes most of the attractions, cross-country skiers can take to the roads and have the whole park to ourselves.
If you're looking for something different, the Ape Cave is an easy ski from where the snowplows stop, and it's not your everyday ski trip. For excellent views of the volcano, ski on up the road from the cave entrance to 3000' Redrock Pass.
The cave, which is a couple of miles from end to end, is very dark. You'll need more than a flashlight, so take a gas camping lantern and an extra backup light or two.
Getting there: Drive to Swift Dam, then turn north and follow the signs to Ape Cave. Park where snow blocks the road and ski the remaining mile or two to the cave. When you arrive at the cave, plunk your skis in the snow, read the signs about how the cave was formed, and walk in.
Update: Since 1993 when this trip report was written, this area has come under Sno-Park parking permit restrictions during winter.
